we have identified and fixed some issues with this kind of queries. The next release will contain the necessary patches. (Due within a few days). Thanks for reporting this to us.

One thing I don't understand though is that you mention SQL text; this is not possible as all the strings that you pass into a dynamic Where() clause will be translated to their respective Expression tree form. Or am I missing something?
